SPECIFICATION forming part `of Letters Patent No. 279,307, dated June12, 1883.

u Applcaionfiled March 5,1963. (Nomodel.)

T 0 all whom it may concern j Be it known that I, THOMAS HiTci-reockAMBRosE, of' the town of' Port Hope, in the county of Durham,in theProvince of' Ontario, Canada, have invented certain new and usefulImprovements in Oar-Couplers, ot' which the following is aspecification.

The object of' this invention is to provide a simply and cheaplyconstructed car-coupler, so arranged that an ordinary coupling link andpin may be used when a car with my self'- acting coupler is to beconnected Ato a car hav! ing an ordinary draw-head; and it consists,essentially, in pivoting upon' one side of the draw-head a hook-shapedcoupler having a weighted end and shaped to fit over a projection formedon the side of' the coupler opposite t-o it.

Figure 1 is a plan of' two draw-heads provided with my improved `hookedcoupler, one draw-head being shown in section, so to indicate theformation of' the recessed projection arranged to receive the flangeformed on the boss on the pivot end of' the coupler. Fig. l shows thepin cast on the coupler.` Fig. 2 is an elevation ofl the draw-head,showing the hooked coupler. Fig..3 is a sectional elevation of adraw-head attached to a car, and showing the coupler hooked up in theposition it will be held in when the draw-head is to be used with anordinary link.

A are the draw-heads, constructed in the ordinary manner, except in thepoints hereinafter specified.

B is a projection cast or otherwise formed on one side of' thedraw-head, and shaped, sub# stantially as shown in Fig. 2, with itsupper surface on an incline of about forty-five degrees, (450,) so as topermit the easy ascent oi' the hooked end ofthe coupler C. This couplerC is pivoted on a pin, D, cast or otherwise formed on the side of' thecoupler opposite to that upon which the projection B is located. It`will be noticed that the hooked end of the coupler C has a swell, a,formed on its side, so

latch quickly the moment its hooked point has passed overthe top edge ofthe projection B.

E is a projection formed on the` side of the coupler, on which the pinDis located. This projection is recessed, as indicated in Fig. 2, so asto receive the flange b, formed on the boss of the pivot end of' thecoupler The fiange, thus fitting into the recess, holds the coupler C onthe pin D,while the projection E, within which the recess is made, formsa strengthening-piece to assist the pin D in withstanding the strainexerted on the coupler.

F is a projection formed on the same side of the draw-head upon whichthe pin D and projection E are located. This projection extends belowthe bottom edge ofthe coupler C in such a position that the coupler Cwill be supported by it in about a horizontal position.

It will be noticed on reference to Fig. l that the coupler C is pivotedon one side ot' one draw-head,while it is pivoted on the opposite sideof the other draw-head, the projections B f being likewise reversed onthe two couplers. This change of location it will be seen is arrangedf'or the purpose oi' permitting the couplers to connect when thedraw-heads come together, the projections F on each drawheadsupportingits particular coupler in such a-po` sition that when the draw-headsapproach each other the couplers C latch over their respectiveprojections B, and the desired connection is thus formed, as shown inFigs. l and 3.

Vhen a car provided with my automatic coupler is to be connected to acar provided with an ordinary draw-head, the usual link, G, andcoupling-link H (see Fig. 3) maybe used. Then so used, the coupler Gmust of course .be held out of' the way, to accomplish which tions c andflanges b, the draw-heads A, ha-v ing pins D, recesses to receive saidflanges b, and inclined lugs B, as and for the purposes set forth.
